Problems of syntax and semantics of verbals

The words of every language fall into classes which are called Parts of Speech. Each part of speech has characteristics of its own. The parts of speech differ from each other in meaning, in form and in function. One of the parts of speech is the Verb. According to content, the verb can be described as word denoting action, the term “action” embracing the meaning of activity (to walk, to speak, to play, to study, process (to sleep, to wait, to live), state (to be, to like, to know), relation (to consist, to resemble, to lack) and the like. According to form, it can be described as a word that has certain grammatical features that are not shared by other parts of speech; they have the category of tense, aspect, voice. According to the function, verb can be defined as a word making up the predicate of the sentence.
